Interaction of BGM as a room acoustics and interior design: an effect of BGM and lighting for evaluation of indoor-room

摘要

Two experiments were performed in order to examine an interaction of room acoustics and the interior design of the room. The room used in these experiments was "interior-designed room." In Experiment 1 two types of BGM were prepared and a change of room evaluation was investigated in terms of types of BGM: Used BGM as a room acoustics were "relaxation music" and "no-relaxation music." Participants were asked to rate the degree of harmony between music and room interior design. Result were that 1) a relaxation music was judged more appropriate for room interior design than no-relaxation music; 2) the room interior design was estimated more calm when BGM was relaxation music. In Experiment 2 the change in the impression and the likes and dislikes concerning this room were examined by using two types of lightening: relaxation lighting and ordinary lighting, 60 participants were asked to rate the impression and the likes and dislikes concerning this room. The results were that 1) the change in the impression from the lighting didn't change the atmosphere formed by the interior design, and 2) the good impression of the room improved when the calm lighting was used. This study showed that both BGM and lighting had an influence on the atmosphere of the indoor room. It can be said that BGM as a room acoustics and lighting can play an additional role in a highly-designed indoor room.
